Merge main into release (#5868)

### General announcements

General fixes and improvements across SOS debugger commands, macOS dump
analysis, and the diagnostic tools since v10.0.721401.

### dotnet-dump / SOS

- **`!gcinfo` GC info v5 support**: The `GCInfoDecoder`/`GCInfoDumper`
sources were synchronized with dotnet/runtime to parse GC info **version
5**, keeping `!gcinfo` working against current runtime builds. (#5862)
- `!threadpool` now properly enumerates assignable work item queues 
- Adds support for 11.0 preview 4 runtimes.
- Much faster SOS-in-lldb memory reads for macOS.
- Fixes in crash dump special buffer detection on Apple Silicon cores.
- Modules that live in the macOS 11+ dyld shared cache are now
identified and skipped during version-string extraction, avoiding
unnecessary symbol-server downloads and timeouts.

### dotnet-gcdump

- **Clearer `convert` errors**: `dotnet-gcdump convert` now emits
actionable messages when the input is not a valid nettrace file,
contains no GC heap events, or holds an incomplete heap dump, instead of
failing opaquely. (#5814)

### Other notable changes

- **Source Link for SOS native libraries**: Added Source Link support
for the SOS native libraries, enabling source-level debugging into the
native SOS binaries. (#5703)
